Practice and tutorial-style notebooks covering my Machine Learning and Deep Learning experiments/projects.

• data/ is an empty folder which is used as a destination for the datasets.
• Notebooks are kept in the root of the project for now.

MacBook Air (M1, 2020)

ARM64 architecture (arm64)

Apple M1 chip 8-core CPU with 4 performance cores and 4 efficiency cores 7-core GPU, 8-core GPU 16-core Neural Engine 16 GB Ram

MacOS Monterey 12.2.1 (21D62)

• conda version : 4.11.0
• python version : 3.9.7.final.0

• tensorflow-macos==2.8.0
• tensorflow-metal==0.4.0

1. First install xcode-select command-line utilities.

   xcode-select --install

2. Installing Miniforge3

   1. Either using Homebrew:

      brew install miniforge

   2. Or, go to the releases section of miniforge's github page, and find the Miniforge3 file which corresponds to your system.

      Like: Miniforge3-4.11.0-0-MacOSX-arm64.sh

      1. Download the file to a folder.
      2. Open a terminal and change to the folder where you downloaded the install script.
      3. Run the command chmod +x Miniforge3-4.11.0-0-MacOSX-arm64.sh (don't forget to replace the file name with the name of the file you downloaded).
      4. Then install from the file by running sh Miniforge3-4.11.0-0-MacOSX-arm64.sh in your terminal.
      5. source ~/miniforge3/bin/activate

3. Initialize Miniforge using the command:

   conda init

4. Use this Conda Cheatsheet to create a conda environment.

5. Activate the newly created conda environment.

6. To use your environment in Jupyter notebooks

   1. conda install -y jupyter (this command installs jupyter)

   2. conda install nb_conda (this command installs nb_conda, which adds conda env support to jupyter notebooks)

   3. And finally, add your environment to jupyter using

      python -m ipykernel install --user --name <env_name> --display-name <display_name>

      Don't forget to replace <env_name> and <display_name> with the name you want.
